Central Arizona DX Association


June Meeting

We are the largest ham radio DX club in Arizona with over 130 members, many of whom are on the ARRL's DXCC Honor Roll.  We have several members who have traveled to distant places to put "rare" countries on the air.  We encourage any ham interested in DXing to join our club and learn about the many aspects of talking to hams around the globe who share this amazing hobby with us.  Founded in 1974, we are an ARRL-affiliated club and a member club of the Amateur Radio Council of Arizona (ARCA).

The June Meeting will be at 7:00 pm on Thursday night, June 7th, at the PERA Club. 

The program will be presented by Dave Jorgensen, WD5COV, “9M0W Spratly Island DXpedition”.  Dave will drive over from his home in Deming, NM to join us for the evening.  He has been on a number of high profile DXpeditions over the years and is a big time DXer at home. 

Please feel free to arrive early to socialize with your friends.  Refreshments will be served at the break.  Guests are always welcome. .

Our Annual Barbecue Meeting featured a program by a radio astronomer, ASU Professor Dr. Chris Groppi.  While I know that some of Dr. Chris Groppi’s technical details were difficult to follow, the basic concept of launching balloons in the dry Polar Vortex above Antarctica for research on star formation was very understandable. 

All of our members who pride themselves on building their own widgets when none are available commercially could relate to Dr. Groppi’s delight in “rolling his own”, including learning how to machine parts down to a 1 micron tolerance.  And, we learned there is a Terahertz radio spectrum that has “star power”.

May Meeting Recap

Our Annual Barbecue Meeting in May was a rousing success. We had a record crowd of 90 attendees, great BBQ food from Famous Dave’s, and a program on radio astronomy that was “out of this world”.  Luckily, the weather cooperated with cool temps and minimal wind. 

A big “thank you” goes out to our club secretary, Bill Poole, AA4Q, who arranged to have ASU Professor Groppi (his friend) come to present this unique program.  It was also Bill’s idea to get Famous Dave’s to cater the BBQ meeting this year.  Thanks also to my other Board members and the many helpers who stepped up to make the event run so smoothly.

The weather outside is heating up and so is the sporadic E propagation on 6 meters.  Several CADXA members were working or trying to work Japan today (May 15th) on 6m FT8.  It was our first JA opening of the season.  Activity should continue through the month of June.  If you are chasing grid squares on VHF, don’t miss a chance to pick up some new ones in the ARRL June VHF contest on June 9-10.

On the HF bands, there has not been much DXpedition activity with the exception of VK9LI on Lord Howe Island.  However, it won’t be long before we have some major excitement with the big one scheduled for late June to Baker Island, KH1.  I am looking forward to that one because I need it on the digital modes.  Make sure your station is ready for pile-up action when our own Ned Stearns, AA7A  will be one of the DXpedition participants with major technical responsibilities.
